Thread: Shopping Cart Error after adding Product to cart

After adding any product to my shopping cart and viewing shoppingcart.aspx, i get the following error: The method or operation is not implemented. Interestingly enough, I do not get this error when running the solution locally. That tells me that something on the server is different, although all the files are identical.



Here is the error in full detail:

The method or operation is not implemented.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NotImplementedException: The method or operation is not implemented.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929

I haven't quite figured out what's going on but we're pretty sure this started happening after ASP.NET 4.5 framework was installed. It works fine if I switch the app pool to asp.net version 2.0 (which is actually 3.5). It works on my local machine with both versions installed but targeting 4.0 in visual studio.

The only place I get an error is on the shoppingcart.aspx page, when I have items in my cart.

We've just added a new KB article that will help with this:

This problem is caused by a change to the default ClientIDMode, but this can be set in the web.config. I have posted the solution in another related post:
